Description
Technical field
The utility model is related to a kind of material-strewing device of cement preheater, belongs to cement manufacture plant technical field.
Background technology
In new dry cement technology, material can be added into the airduct of preheater, and material is carried out using waste heat
Preheating, therefore, spreading plate is provided with preheater airduct, downward slug when preventing descending material from entering heat exchange airduct, under promoting
Rush splashing, dispersion that material is rushed to blanking plate, it is ensured that material sufficiently uniformly exchanges heat in heat exchange pipeline.
Spreading plate is typically obliquely arranged on preheater and is in charge of side, is provided with material inlet and material outlet, material inlet
Connected with feed facility, material outlet is connected with airduct, the residual heat air current in airduct upwards, using downward material with it is upward
The collision of thermal current is broken up, heated material, and the uniformity for being sprinkled into material in airduct is better, and material is more abundant with hot air impingement, heat
Gas is better to material heating effect, and energy-saving effect is also better.
At present, the principle of conventional material-strewing device is the spreading plane that the impulse force fallen using material strikes material-strewing device
Upper automatic dispersion, such as Publication No. CN203443355U, the utility model of entitled " spreading plate ", structure is produced in reality
In, because material gets off rear impact not enough, or it is uneven cause the material can not to scatter or into strand, cause heat transfer effect
Undesirable, it is impossible to accomplish uniform spreading, quality of material stability is not good enough.
Utility model content
The utility model aims to solve the problem that material-strewing device spreading is not uniform enough in the prior art, and product quality stability is not good
A kind of problem, there is provided material-strewing device of new cement preheater, by spreading the setting of blowing apparatus, can equably be sprinkled into wind by material
Guan Zhong, solves material and is heated uneven technical problem.
In order to realize foregoing invention purpose, the technical solution of the utility model is as follows：
A kind of material-strewing device of cement preheater, including feed opening and the spreading plate with guiding gutter, it is characterised in that：It is described
Material-strewing device also includes blowing device, and the blowing device includes multiple discharge pipes, and the port of export of the discharge pipe is led with described
The notch of chute is corresponding.
Operation principle of the present utility model：When needing preheating, blowing device is opened, after material falls from feed opening, passed through
During spreading plate, by the wind of each discharge pipe equably to fore blow, that is, the uniform preheating of material is realized.
In order to the utility model is better achieved, further, the angle between the spreading plate and the feed opening is
150~160 °.
In the utility model, the angle between the spreading plate and the airduct of preheater is 90~99 °.
In the utility model, the discharge pipe arrival end connects the tail gas exhaust machine of preheater, can will have certain waste heat
Tail gas reused, improve heat utilization rate.
The beneficial effects of the utility model：
（1）Compared with prior art, the utility model changes the angle of repose of material by setting blowing device, can be effective
The uniformity of spreading in preheater airduct is improved, makes the material preheating into Gas inlet tube more abundant, so as to improve the quality of product
Stability.The utility model changes smaller on original device, and simple structure is workable.
（2）In the utility model, the angle between spreading plate and the feed opening is 150~160 °, further, is spread
Angle between flitch and the airduct of preheater is 90~99 °, and the further preferred of the angle prevents the descending material of tremie pipe
The problems such as what downward slug was caused during into heat exchanger tube collapse material, realize the uniform beneficial effect of material dispersion.
（3）Angle adjustment adds blowing device, makes heat exchange more abundant, and the thermal efficiency is conducive to the drop of energy consumption using higher
It is low, meet national energy-saving emission reduction policy.
